cuFalcon

This repository contains the artifact for our paper "cuFalcon: An Adaptive Parallel GPU Implementation for High-Performance Falcon Acceleration".

This project contains CUDA-accelerated implementation of the Falcon post-quantum signature scheme. It includes two parameter sets:

• cuFalcon_512: Falcon-512 implementation
• cuFalcon_1024: Falcon-1024 implementation

Running the Code

For each parameter set, navigate into the corresponding folder and run the provided script to perform signing and verify correctness:

# For Falcon-512
cd cuFalcon_512
./run.sh

# For Falcon-1024
cd cuFalcon_1024
./run.sh
